DiabloSport MAFia with Tuning Software - Manual

Using the MAFia with Tuning Software
The best way to use the MAFia is to tune the vehicle for idle and cruise and lower RPM ranges at
wide open throttle rpm before you install the MAFia.
Once you have the car running properly install the mafia and set it to 0.
Start the vehicle and make sure that it runs just like it did before the installation of the mafia.
(check fuel trims and load)
Once you have checked to make sure the vehicle runs the same, you can set the mafia to the
desired setting to support the horsepower you intend to make.
Make sure the key is off whenever you change the setting on the MAFia.
You will now apply the necessary changes to your tune to accommodate for the new setting on the
MAFia. This can be accomplished two ways.
Method One – works for all tuning software
Using the settings chart, reduce the following parameters in your software by the correction factor.
Fuel Injector Low Slope
Fuel Injector High Slope
Air Mass Displacement of one cylinder
Setting Correction Factor
